Figure the size of the gun needed to use the autoloader, the weight and cost of support for such a gun and it becomes something that is not nearly as reliable on the battlefield.


Yea, and I have seen some pretty freaky videos from the development of the Korean K9 155mm SPG where during development the autoloader failed to ram the round home and as the plunger extracted during a HA mission (it can autoload during HA fires which is pretty cool) the round slipped out and fell onto the floor of the gun... :?

Cool mod, but when you shoot Excal, your frontal has to be clear for 100 meters because the debris falls after the fins fold out. So you will not be firing over another gun unless you are 100 meters clear.

That mission is a high angle so that is correct as every EC mission is a high angle.


Yea, I need to simulate the fin covering coming off haha. When combined with another mod in the community, ACE, the over pressure there is pretty high anyways. I'd never do that in a real game (just testing in that video, obviously, with all the debug info and color trails).

Currently working on the sight unit for when the AFCS breaks down, so you have to go lay stakes, collimator or find a DAP. Also reworking the loading interface to be more interactive (its just a boring menu now where you chose round, charge, fuze type (and time if required)). Going to have some nice drawings of the rounds: http://raceriv.com/arma2/155mm_drawings.jpg (don't mind that the M110 round has a M782 in that drawing, I know it should be an M767 ET fuze, just haven't uploaded the latest images).


Currently we all use the PDFCS now, but the site can be found here: http://www.scribd.com/doc/13770861/Howi ... 5mm-m109a6

That would suck, at least the Nato Fuzes do not arm unless they spun at a certain velocity so many times so you could drop it directly on the fuze and in theory it wont go off lol.

Haha, pretty much read the TM front to back a few times. Our FCS is pretty generic, mainly because with out the POC we had to have an interface for guns to enter target grids manually. Working on the POC though with distributed fire missions from the POC to the platoon, but it will probably still be more generic than the actual interface (though maybe someday I will do it by the book haha).

To shoot degraded like that takes longer, because you have to manually enter the information and the #1 man then has to do the gunners job with the charge.

Here is your degraded info: http://www.globalsecurity.org/military/ ... 0/appa.htm

I have a few direct fire videos from the range (degraded) on my facebook. Yes, it can be done - the elevations with charge and round combo's are displayed on a plate for the Chief and or Gunner to read.


That's pretty neat. I'm a former 11B so I dont know a whole lot about arty. It's great to know you guys had our backs when the **** goes south though :D

Maximum High. Refers to the highest charge in the MACS system, which has two types low and high charges, and so the maximum is call max hotel, or 5 Hotel for the M109, which is the same charge force as the older M203A1, aka Super 8, aka charge 8 whitebag, etc.

For MACS it goes 1 Lima, 2 Lima, 3 Hotel - 6 Hotel (6 was going to be used in Crusader).

Do you have data on cold war era automated fire control, like Manevr system?
